Can someone please advise me on the current method ROAR uses of teching a Brushless Motor? In the past, motors were teched via Inductance and their values in microhenries. Newly approved motors do not have that information released to the public (at least that I have found). I was told by Ron Schuur before his departure as ROAR Tech Director that ROAR was changing over to teching resistance as the new method of verifying legality of motors, as Inductance does not mean anything to the performance of the motor. Is this information correct? If so, where can I find the minimum resistance figures of each wind of ROAR Spec Motors? Also, what equipment is used by ROAR to check this, and must a race organizer use the same equipment to legitimately check and tech motors for ROAR Legality?

Also, what is the situation regarding legality of the 13.5 and 10.5 D3.5 SPEC Motors after the April date that was set forth in the settlement? I was under the impression that ROAR knew of the 13.5 and 10.5 motors being built from wire larger than legal just as the 17.5 motor was(not accusing, simply inquiring). I am under the impression that these motors will still remain legal. Is this correct? If so, WHY? I believe that ROAR's sister sanctioning body EFRA found the 10.5 motor to use wire too large resulting in the exclusion of the motor in competition. ( http://news.efra.ws/fileadmin/news/2...3.5%20pdf2.pdf ) If this motor, which has been found to have wire that does not meet the written rules, is allowed to compete indefinitely, then how can any other motor manufacturer compete? Can other manufacturers submit motors with the same size wire and be approved? As a ROAR Affiliate company who sells brushless motors under the ROAR Approval, I simply cannot comprehend how this is tolerable from such an esteemed sanctioning body.

Thank you in advance to your replies!
